bad at manual tasks

6. What is DevOps?
DevOps (a clipped compound of
"development" and "operations") is a culture,
movement or practice that emphasizes the
collaboration and communication of both
software developers and other information-
technology (IT) professionals while automating
the process of software delivery and
infrastructure changes.

8. Software Takes More than Writing Code
Quality Assurance
Operations
And more:
Security
Production Support
Product Management

9. Testing Alone is incredibly Complex!
Unit
Testing
Integration
Tests
Functional

10. Traditional Software Development Teams
Silo’ed: different departments, different
budgets, different managers
Different rules!!!
DevOps is a cultural outcome that
breaks down these silos!

11. You can’t “do” DevOps
Like I said: DevOps is a cultural outcome - you can’t really “do” DevOps
But! You can do:
Continuous Integration
Continuous Deployment
Agile Software Development

12. Continuous Integration
“Continuous Integration (CI) is a
development practice that
requires developers to integrate
code into a shared repository
several times a day. Each check-
in is then verified by an
automated build, allowing teams
to detect problems early.”

15. Continuous Delivery / Deployment
DevOps: Cultural approaches & technical practices to do all this.

16. Why is this all important?
“Software is eating
the world.”
“Every business is in
the software business.” “It’s an
application economy.”
